;This invention relates to multiple spindle metal working machines, more particularly to the frame thereof, the object of the inventlon beingto, provide an improved open frame 5 rigid in constructionfor the supportof the work spindlecarrienzsliding tool carrier and their operating mechanisms so constructed that the chips from the work carried bythe spindles during the operation of the tools 19 thereon willfall uninterruptedly' into a pan located at the base of the machine In multiple spindle machines, as usually constructed, the frame and the working parts very materially interfere with the tooling of the machine and the eifectiveoperation of the machine in that theyinterfere with the uninterrupted fiow. of the chips from the work and consequently often retard the productlon of the machine. 1

The capacity of automatic multiple spindle screw machines has been very materially 1n- .creased'by reason of the increased speed of the tools'and the-high speed of the cuts made thereby and the employment of high gradesteel, all resulting in a considerably larger quantity of chips from the. work and, there fore, anything that interferes with thefalling thereof into the pan helpsto retard the production of the machine, increases the'ditficulty of removing the chips and preventsthe continuous operation of the machine and consequently it is necessary in the ordinary running of the machines that the operator continuously removethe chips and turnings to prevent breakage of the parts or interference with the work. 7

Therefore, the object of the'presen't invention is the provision of an improved frame 40 having means particularly adapted to facilitate the lodgement of the chips and turnings in the pan and which means also increases the rigidity of the frame without in any way interfering with the accessibility of the tools. In the drawing accompanying and forming a part of this specification Figure 1 'is' a front view of-the machine; I a

Fig. 2 is a cross sectional view taken on line 22,Fig.. 1; and- 5.0 3 is a detail view illustrating a somewhat difierentway of securing thei' f-rame parts together.

Similar characters of reference indicate corresponding partsin the several views."

Before explaining in detail the present'im;

provement and modeof 1 operation thereof, I

desire to have it understood that theinvem' 'tion is not limited to the details of construcextend, each preferably of boxformation suitably spaced apart thus leaving the ,frame practically 1 open from side to ,sidebThe standard 6 supports the usual indexible work spindle carrier 9 having rotary work spindles 7118 77,, and 'h and the usual cross slide is, while the upright or standard-0 carriesv the usual driving mechanism for the i work spindles. i

These two standards are shown connected together at their top. by a tie member 12. Ex-

tending from one standard to the, other is a hollow tube through which passes'the rotary spindledriving shaft and located a sliding tool carrier 2' which" may have a guide arm guided by means carried by the tie member d. i V a For rigidly connecting the two standards or uprights b and 0 neartheir bases thereby giving rigidity to the frame, a roofshaped member 6. is located therebetween, and below the apex thereof and through the standards a main cam shaft m protected by the member e from the chips and turnings of the work. p 7

This roof shaped member may be formed integral with the standards Z) and c if preferred or may be bolted thereto. byfscrew bolts f, (Fig.3), the integralformationbeing preferable in, the smaller sizes. of machines. By means of this roof shaped memon which tube is passes whereby itisdoes not interfere with the tooling of the.

machine.

The upper or'apex portion of this member 6 is located directly under the spindle driving shaft and is thereforein position to properly deflect the chips and turnings fallingfrom the stock and thus prevents the lodgement and piling up of the chips where they would interfere with the proper operation and speed of the machine.

It is to be understood that by describing in detail herein any particular form,'structure orarrangement, it is not intended to limit the invention beyond the terms of the several claims or the requirements of the prior art.

' Having thus explained the nature of my said invention and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it may be made, or all ofthe modes of its use, I claim:

2. A multiple spindle automatic machine having a base and a chip receiving pan located around the outside of the base, two upright standards secured to said base and spaced apart to provide an open sided frame and adapted to carry an indexible work spindle carrier and its co-operating mechanisms,and a bracing roof formed member between said standards and below said work spindle and in position to deflect chips and turnings from the work into the chip receiv ing pan.

3. A multiple spindle automatic machine having a base and a chip receiving pan, two upright box formed standards secured to said base and spaced apart to provide an open sided frame and adapted to carry an indexible work spindle carrier and its co-operatin'g mechanisms, and abracing roof formed member'between said standards and below said work spindle and in position to deflect chips and turnings from the work into the chip receiving pan. c
